Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large skillet over medium heat. Add 1 minced garlic clove and sauté for 30 seconds until fragrant. Add 4 cups chopped fresh spinach and cook, stirring, until wilted and most moisture evaporates, about 4-5 minutes. Remove from heat.
  2. Step 2: In a bowl, combine cooked spinach, 1 cup crumbled feta cheese, 3 sliced green onions, 2 tbsp chopped fresh dill, 2 tbsp chopped fresh parsley, 1/2 tsp salt, and 1/4 tsp black pepper. Mix well.
  3. Step 3: Preheat oven to 400°F. Roll out 1 thawed puff pastry sheet on a lightly floured surface and cut into 4 equal squares.
  4. Step 4: Place about 2 tbsp of the spinach and feta filling in the corner of each square. Brush edges with beaten egg and fold pastry into triangles, pressing edges to seal.
  5. Step 5: Place triangles on a baking sheet lined with parchment paper. Brush tops with beaten egg. Bake for 18-20 minutes until puffed and golden brown.
  6. Step 6: Let cool slightly before serving warm as an appetizer or light meal.
